Be it known that civil engineer, subjectof the King. of den, residing at 1l Uppsalagatan, helm, Sweden, have invented certainnew and usefullinprovements in Gas-Analyzing Apparatus, of which the following *is* specification. Y

The present invention refers to-gas ana-eQ ly-zing apparatus, 1n which the gas or 1t s conL stituents are chemically or mechanical changed or in which one or more constitu ents are separated from a gas y temperature or the percentage of humldity are to be changed, or to gas analyzingap y,paratus serving any otliery'similar purpose,` and consists in the speed of the gas llov'vf'` or liquid iow in oneA` direction being reduced while the flow in the opposite direction r'e mains unaffected. This is attained` by sorting a resistance to the gas flow in one o two directions of ow. p time necessary for changing the coin ositon yof the gas or its 'constituents is gain re f. erably the device is arranged insuch a place that the gas will reach the primary measuring vessel after having passed said device.

Some embodiments of known gas analyzing apparatus to which the invention is applied are shown in Figures L5, where the device is schernaticallyV represented as a con traction in the piping. Figs. 6-7 show two embodiments 'of the device, in a larger scale.

In the apparatus according to Fig. 1kb indicates the-primary measurin vessel '1n rises and falls t rough rthe V medium of. the? iessel c which forms a part of, a pumpingdevice, for insthnceaccording to the Gjrrnandiatent No.2226 ,5 f12. d and e indicate liquid seals, pipeL g an absorption receptacle and 'ha supply pipe for the gas to be analyzed. and il are conduits for the pressure fluid opera-tin the pump, Through the pipe. lc the liquld enters' the measuring vessel b.

At z .the branch again opens into the supply pipe. Between the exhaust and inlet openings u and a, there is an adjustable flap valve y, arrangpd in the su 'ply pipe. t e speed of t e flow in a direction opposite to that of the-arrow will not be -inliuenced, as the gas or the liquid can pass freelyl through the ball valve and thus through t e branch fv. At the How in the and the setfscreuv` ftf, and s the exhaust reed ofvllow therefore will be determined y the adjustment of the fiap valve y. If the flap `valve y -is the ball valve t1 will not be operated. If, on the other hand, the flap valve is entirely closed, the retarding elect of the "same is the greatest, as in this case the whole quantitiy of the gas or the liquid g 2 shows an apparatus of another kind than one of Fig. 1, whereinthe pipe e directly opens into the measuring vessel b.

is shown here only schematically, may in accordance with Fig. be arranged in the pipe e at a2 or in the pipe /c at (1,.

In the arrangement according to Fig.- 3 the pipe e opens into the measuring vessel b.. The device may, as in Fig. 2, be arranged at a. v

In the arrangement according to Fig. 4 the gas exhaust pipe 1 opens into the measuring vessel b which consists of two communicating vessels. As in Fig. 2 or 3, the device may be arranged at a2 or a in the pipe e or c.

'According to Fig. 5 the measuring vessel b is connected with the vessel p through the pipe lc. Water or another working Huid enters through the ipe m, whereby an increase ofpressure ta es place in the vessel n. This is transmittedy to the vessel p and effects a rise of the liquid in the Apipe 1'. At, the same timethe hquid also risesin k and b.

s soon as the pi e r is takes place in it w ereby the over pressure o and p ceases. The liquid thus falls in lo and b. In this arrangement, the device may be arranged in the pipe r, for instance yat a5, whereby it is attained that theover pressure in p as well as the liquid in la will fall comparatively slowly -so that the gas will be sucked in through e only slowly.

In the arrangements shown, the device infilled, an action dicated as a contraction is always supposed to be.stationary.

In certain cases, however, it may be advantageous to make the device detachable or .after absorption and in which the flow of gas through the iping is effected by means of a rising and fiilling li uid, characterized in that an obstruction, adjustable byhand, is arranged in the piping, said resistance having such a construction, that the speed of flow of the gas, or the liquid respectively, is reduced in one direction but is unaffected in the other direction.

In testimony whereof I aiiix my signature in presence of two witnesses.
